• Radial Ribbed T-Yoke Dissipates Heat and Decreases Distortion

The MTX Audio 55 Series subwoofers are the perfect solution for improving your car sound quality while taking up little space. Their low profile means they do not need a large enclosure and will still deliver powerful bass. How do they do this? With an improved surround compared to traditional Half-Roll surrounds, expanded surface area and reduced distortion due to progressive suspension controls. With over 40 years of audio experience, MTX Audio makes sure and knows how to create quality audio with their products, and the 55 Series is no exception!

The MTX Inverted Apex Surround increases the surface area of the sub to allow for more air movement, accurate bass reproduction and higher SPL. Traditional Half-Roll Surrounds have an inherent wrinkling when reproducing bass due to the physics of its motion, which causes distortion. The Inverted Apex Surround moves symmetrically through both positive and negative cycles which eliminates this type of distortion.
Progressive Suspension control the excursion of the subwoofer at high power levels which reduces distortion. Eliminating this 3rd order distortion means you can play your music loud and rely on your subwoofer to take of itself.
Two features really make sure the MTX subwoofers stay cool: the Spider Plateau Venting and the Radial Ribbed T-Yoke. The Spider Plateau Venting is a mechanical cooling process that targets cool air at the voice coil. This means the subwoofer cools itself as it is playing. The Radial Ribbed T-Yoke acts as a heat sink that dissipates heat and decreases distortion.

OK wire if you like red wire
I received this wire because when I bought my Image Dynamics speakers from Sonic the description said it included speaker wire in the box, but when I received them there was none. I called Sonic and they sent this wire to make up for the error. I later called Image Dynamics and found out that they no longer include speaker wire with their speakers so Sonic if you are reading this you can update your description and pictures on the ID speakers to NOT show speaker wire. For the record I bought the Image Dynamics CTX65cs and the CTX4 speaker sets. Great speakers by the way. Thanks Sonic for all your great products and sound advice, no pun intended:)

Giveaway
At the price they are asking,($40 shipped), this is a no-brainer. You'd be very hard pressed to buy the MDF used in this enclosure for the price they are selling the complete box for. Its true 3/4", ( I laid a caliper to it to check), and its advertised dimensions and airspace are spot on.

Great bass
Bought this for an old punch 2 I had sitting around that I put into my sons car. Previously it was in a small truck box for an s10. Couldn't believe the difference that this box made. The sub is getting 200 watts from the little fosgate amp that I had for it but it is twice as loud as it was in my truck with no distortion. Obviously I had it in way to small of a box before. I got one happy kid though.

Usable
The wiring has done me right so far but the only thing I don't like is the speaker wires. You have to carefully split it so the wire doesn't show. Other than that minor thing everything was great and a great value!

A winner
This is just what the woofer doc ordered. The poly fill is already installed. The black carpet looks great. I'm installing a Rockford T-1 dual 4 ohm 12 in the box. I'm anxious to hear how this is gonna sound in my Mark VIII.

Exactly what I needed.
I purchased this box to house an Alpine type E sub. I had originally intended on building my own box, but after looking around at the prices of MDF, I found this box, I literally couldn't purchase the materials cheaper than buying this. It's sturdy, and is a perfect match for my sub. I am extremely pleased with my purchase, and would recommend it to anyone looking for a very well built, sealed, enclosure.

Good box!
For a pre built box it does the job very well! The poly fill is useless if you need a bigger box just order a bigger box... No leaks what so ever. I did replace it for a custom built ported box.
